Revisions to Preliminary Prospectus

This Free Writing Prospectus is being filed to advise you of the availability of a revised preliminary prospectus dated February 6, 2024 (the “Preliminary Prospectus”), and to provide you with a hyperlink to Amendment No. 2 to the Registration Statement on Form F-1 (File No. 333-276589), which includes the Preliminary Prospectus.

BBB Foods Inc. (the “Company”) has made revisions to the previously filed Registration Statement in order to update certain Class C common share figures relating to the 2004 Option Plan and equity bonus amounts to consistently reflect the 3-for-1 forward share split that will be effective immediately prior to the completion of the offering.

More specifically, the Company has updated the disclosure to reflect that 43,186,224 Class C common shares are issuable upon the exercise of options granted under the 2004 Option Plan as a result of the 3-for-1 forward share split and revised the related strike prices on page 120. Additionally, the Company has updated the figures on page 61 relating to dilution, and on pages 119, 120 and 121 relating to the 2004 Option Plan, Liquidity Event Bonus Plan and Founder Liquidity Bonus calculations, respectively, in each case to reflect the aforementioned share split. The 3-for-1 forward share split adjustment and the Company’s IPO Reorganization similarly affect the earnings per share calculations on a pro forma basis as indicated on pages 20 and 21.

You should read the entire Preliminary Prospectus carefully, including the section entitled “Risk Factors” and the financial statements and the related notes before you decide to invest in the Company’s Class A common shares.
